Hi, Dan,
I used AmberTools 1.2 / tleap to generate this some time ago. But also
tried using 1.5 recently. It behaved the same. The topology file is
too big to send by email (this is a big system). Instead, I attached a
figure to show what is going on. Red dots are waters. Cyan and blue
balls are ions.
The input for tleap as follows:
source leaprc.ff03
source leaprc.GLYCAM_06
X = loadpdb 3ije_mod.pdb
solvateBox X TIP3PBOX 15
addIons X Na+ 241 Cl- 203
charge X
savePdb X 3ije_wb.ff03.pdb
saveamberparm X 3ije_wb.ff03.prmtop 3ije_wb.ff03.prmcrd
quit
Thank you!
Wei
